Application tiled June 1L', 18S-2,

To /rZ/ w71 ont may concern:

Be it known 'that I, HENRY A. ADAMS. a citizen ot' the United-States, residing at Sandwich, in the county ol' De Kalb and State ot' Illinois, haveinvented certain new and use ful improvements in Harvesting-Machines, which are fully set forth in the following speciiication, reference being had to the accoinpanying drawings, in which- Figure l represents a side elevation at the grain side of the machine, showing the grainwheel and the parts adjusted thereto; Fig. 2, a transverse section ot' thesaine on an en.- larged scale, and taken on the linexx, Fig. l; Fig. 3, a plan section on the saine scale, taken on the line y y, Fig. l; and Fig. 4, a plan view on a diminished scale, showing the relation ofthe several parts.

My invention relates to machines for harvesting grain, and particularly to the means by which the grain-wheel is supported and attached tothe machine, whereby it is arranged nearly in line with the divider, and

may be readily adjusted.

Difficulties have been experienced in harvesting-machines with the grain-wheel constructed and arranged inany ol' the well-k nown ways. 1f the grain-wheel, with its axle-block and adjusting devices, are all arranged on the outside of the end beam, the wheel is projected so far beyond the outer end ot' the platform on which the grain falls that it has been found very difficult to make the divider gather enough to protect the standing grain from the encroachments ot' the wheel, and consequently a line of grain is likely to be trodden down and lost. If, on the other hand, the wheel and its attaching and adjusting devices are all arranged inside of the beam, the space required for their accommodation is such that the platform is encroac-hed upon, so as to interfere with the proper delivery ot' the grain thereon. y

My present improvement is intended to o'vercome these diiculties, and I will proceed to describe in detail the construction and operation ot' the invention as I have carried it out practically in one way, and will then point out definitely in thc claims the special improvements which I believe to be new and desire to secure by Letters Patent.

is the improvement relates only to the (No model.)

grain-wheel, I have shown in' the drawings and shall describe only so much ofthe niathe invention, for the improvement can be applied to any harvestingmachine, whatever may be the construction ot' the other parts.

In the accompanying drawings, A represents the platform ol' a harvesting-machine; B, the tinger-beam; C, the divider, and l), the grain-guard at the grain end ot' the machine, and all of these parts are ot' any ordinary construction. The outside beam, E, of the platform-frame is also of ordinary construction, except that it is divided at the point where the grain-wheel is to be located; or, in other words, is made of two parts, c e', as shown in Figs. l and 3V ot' the drawings. These two sections are joined together by a metal yoke, F, which is provided with iianges at each sections are rmly bolted to the yoke. The yoke has a long central opening, which stands vertically when the parts are secured together, as shown in Fig. l olthe drawings, and is provided near its outer lace with a tlange, f, projecting inward around this opening, inside of wh1ch it is also provided with a toothed rack, j", on one side ot' the opening or slit in the yoke, preferably the front. side, as shown in the drawings. This yoke device provides a means for supporting the stub-axle G on which the grain-wheel 1s mounted. The axle is arranged within the opening in the yoke, and has a toothed pinion, l-l, secured to it, so as to also stand within the yoke and inside of the iiange of the latter, the diameter ofthe pinion being about equal to the width of the yokeopening, and arranged so that the pinion engages with theA rack on theyoke. The pinion has a short bossJz, on its outer face ol'less diameter than the body, so as to enter the space within the iiange on the yoke. boss is about equal to the thickness ofthe flange, though it should be just a trifle less. The end of the axle G outside of the pinion is cut down and provided with a square section or shank, g, to which is tted loosely an adwhich is of such size as to tit within the outer liange ofthe latter. This Wheelis held in place by means of a nut, J, which, is turned, upon chine as is necessary to an understanding of 55 side,by which the inner ends ofthe two beain- The depth of this justing-wheel, I, the inner or hub portion of loo` portion ofthe yoke against the outside ot' the the threaded end g of the axle. The wheel is provided with radial arnis z', in which are sockets t" for the reception of a haud-lever, by which it niay be turned to adjust the platt'oi'n'i, as will presently be described. The inner end ofthe axle projects inward beyond the yoke, and the gra-in wheel K is mounted loosely thereon inside ot' the beain and between it and the grain-guard. lt will be seen that whenever the nut J is turned up against the adjusting-wheel the inner face ot' the latter is clauiped against t-he tlange ofthe yoke.and by this clamping device the position ofthe yoke is iixed at any point desired. When it is desired to adj ust the height ot' the outerend of the platform, this fastening -nut is loosened "slightly, a hand-lever Vis inserted in one of the arnis ot' the ailjusting-wheel, and the latter turned in the proper direction to rotate the axle and pinion thereon in such a way as to raise or lower the yoke and beani attached thereto by the engagement of the pinion with the rack, and when the proper adjustment is secured the nut is again turned up, thereby clamping the axle to the yoke and holding it in the position desired, as above described.

'lhe fastening and kadyustinfa; devices ol" the grain-wheel are thus brought substantially in the saine plane with the outer beain, and are readily reached and manipulated tor any ot' the usual purposes. At the saine tiniethe grain-wheel is arranged within the beain without requiring any substantial enlargement ot' the space between the latter and the grainguard, and obviously the tread ot' the wheel is but slightly, it' any, outside ot' the line ot' out, so that the outward inclination ot' the divider required is very slight, in oi'der to bring it in line with the grain wheel, asshown in Fig. et 0f the drawings. The diiiiculties nien tioned above are thus obviated without inA eliningr the wheel. and the outer support ot' the platt'orni is as strong as when the neain is niade entire.

Obviously there are dill'erent ways of ap plying niy iniproveineijt to the machine, and l do not contine inyself to all the details ot' construction and the specitic devices set loi-th in the description above, provided the niain elements ofthe iinproveinent are retained by which Iain enabled to secure the results al ready set forth.

In the drawings, the grain-wheel is shown arranged inside of the beain, and this is the arrangement described above. I. do not wish to be understood, however, as restricting iny invention to this particular arrangement, for like beneficial results are obtained by arranging the wheel on the outside of the beain. \N hether the grain-\vheel is placed inside or outside ot' the bcain, the advantages gained by dividing the beam and placing the attaching and adjusting devices between the sections ofthe beain and in line therewith aresubstantially the saine. In either case the wheel is brought close to the beam, so that it' on the l` outside there is only about the space occupied bythe wheel alone to protect by the galhei" ot' the divider, and it' on the inside there is onlyasiinilarslight encroachment on the p1atforni.

rlhe division of the end beaui and the arrangement ol" the attaching and adjusting devices ot' the grain-wheel are the essential l'eattires of iny invention, and the details ol" construction and arrangement inay be varied in inany different ways. t

Having thus described niy invention, what I claini as new, and desi reto secure by Letters Patent, is-

l. ln a harvesting-inachine, a divided end beani, a coupler or connecting device i'or uniting the parts of the beaui, and ineehansin for attaching the grain-wheel to the traine, a-rranged, nianly, between and substantially in line with the sections oi' the end beain, substantially as and tor the purposes set i'ortli.

2. In a harvesting machine, a divided end beani, in coniliination with a yoke to which the adjacent ends ofthe beam-sections are secured, the axle ot'4 the grain-wheel passing through the opening in and secured to the yoke. and a grain-wheel inounted on the axle at one side ot the beain, substantially as and for the purposes set t'orth.

3. The beam-sections e c", in combination with the nietal yoke F, axle G, passing through the opening in said yoke, grain-wheel K. ar ranged at one side ot' the yoke, and niechanisni whereby the axle inay be adjusted up and down in the yoke and secured in any position dosired, substaiit iahy as described,

et. The bezint-sections, in combination with the yoke F, provided with a ilange, f, and toothed rack j", axle (l, grain-wheel K. and pinion H, substantially as describd.

5. The yoke F, provided with tiange fand rack f, in coinbiuaton withthe axle G', grainwheelA K, pinion H, adjusting and clamping wheel l, and fastening-nut J, substantially as described.

6. The beam-sections, in combination with the yoke l", to which the sections ai'e secured, the axle passing through said yoke, the grainwheel n'iounted on the axle at one side ol" the beam, the linger-bar, and the divider, all arranged a'nd operating substantially as described.
